The graph of the linear equation can be seen in the image below.

<h3>How to graph the linear equation?</h3>

Here we have a linear equation:

y = -x

To graph it, we just need to find two points and the line, and then connect the points with a line.

Evaluating in x = 0, we get:

y = -0 = 0

Then we have the point (0, 0).

Evaluating in x = 1 we get:

y = -1

So we have the point (1, -1)

Now we just need to graph these two points and connect them with a line, the graph can be seen below.

The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 246.9 and a standard deviation of 6

belka [17]

Answer:

The approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 177.6 and 316.2 is 68%.

The approximate percentage of women with platelet counts between 39.0 and 454.8 is 99.7%

Step-by-step explanation:

Mean : $\mu = 246.9$

Standard deviation : $\sigma = 0.49$

Empirical rule :

1 ) 68% of the data lies within 1 standard deviation of mean

This means 68% of data lies between: $\mu-\sigma$ to $\mu+\sigma$

2) 95% of the data lies within 2 standard deviation of mean

This means 95% of data lies between: $\mu-2\sigma$ to $\mu+2\sigma$

3) 99.7% of the data lies within 3 standard deviation of mean

This means 99.7% of data lies between: $\mu-3\sigma$ to $\mu+3\sigma$

Now to find the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 177.6 and 316. 2

Use rule 1: $\mu-\sigma$ to $\mu+\sigma$

$246.9-69.3$ to $246.9+69.3$

$177.6$ to $316.2$

So, according to rule 1, 68% of the data lies within 1 standard deviation of mean i.e. 68% of the data lies between 177.6 and 316.2.

Now to find the approximate percentage of women with platelet counts between 39.0 and 454.8?

Use rule 3: $\mu-3\sigma$ to $\mu+3\sigma$

$\mu-3\sigma$ to $\mu+3\sigma$

$39$ to $454.8$

So, According to rule 3 : 99.7% of the data lies within 3 standard deviation of mean i.e. 99.7% of data lies between 39.0 and 454.8

Help with this question, please!! I don't understand!

kondor19780726 [428]

Answer:

FE = 30°

Step-by-step explanation:

arc FGC = arc FG + arc GB + arc BC

220° = 90° + arc GB + 70° . . substitute known values

60° = arc GB . . . . . . . . . . . . . subtract 160°

External angle A is half the difference of arcs EG and GB:

30° = (1/2)(arc FE +90° -60°) . . . substitute known values

60° = arc FE + 30° . . . . . . . . . . . multiply by 2 and simplify

30° = arc FE . . . . . . subtract 30°

_____

The key to this problem is the relationship between external angle A and the measures of the arcs it subtends.

The graph of a logarithmic has a vertical asymptote at x=4 , contains the point (e+4, 1) , and has an x-intercept of 5. Which fu

Contact [7]

Answer:

f(x) =ln(x−4)

Step-by-step explanation:

We can easily solve this question by plotting each of the graphs and verify the conditions in the problem,

Please see attached image.

The answer is the first option

f(x) =ln(x−4)

Which corresponds to the function ln(x) shifted four units to the right.

Besides,

f(e+4) =ln(e + 4−4) = ln(e) = 1
